<a name="gtk-High-level-Printing-API.description"></a><h2>Description</h2>
<p>
GtkPrintOperation is the high-level, portable printing API. It looks
a bit different than other GTK+ dialogs such as the <a class="link" href="GtkFileChooser.html" title="GtkFileChooser"><span class="type">GtkFileChooser</span></a>,
since some platforms don't expose enough infrastructure to implement
a good print dialog. On such platforms, GtkPrintOperation uses the
native print dialog. On platforms which do not provide a native
print dialog, GTK+ uses its own, see <a class="link" href="GtkPrintUnixDialog.html" title="GtkPrintUnixDialog"><span class="type">GtkPrintUnixDialog</span></a>.
</p>
<p>
The typical way to use the high-level printing API is to create a
<a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation"><span class="type">GtkPrintOperation</span></a> object with <a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-new" title="gtk_print_operation_new ()"><code class="function">gtk_print_operation_new()</code></a> when the user
selects to print. Then you set some properties on it, e.g. the page size,
any <a class="link" href="GtkPrintSettings.html" title="GtkPrintSettings"><span class="type">GtkPrintSettings</span></a> from previous print operations, the number of pages,
the current page, etc.
</p>

Then you start the print operation by calling <a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-run" title="gtk_print_operation_run ()"><code class="function">gtk_print_operation_run()</code></a>.
It will then show a dialog, let the user select a printer and options.
When the user finished the dialog various signals will be emitted on the
<a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation"><span class="type">GtkPrintOperation</span></a>, the main one being ::draw-page, which you are supposed
to catch and render the page on the provided <a class="link" href="GtkPrintContext.html" title="GtkPrintContext"><span class="type">GtkPrintContext</span></a> using Cairo.

By default GtkPrintOperation uses an external application to do
print preview. To implement a custom print preview, an application
must connect to the preview signal. The functions

Runs the print operation, by first letting the user modify
print settings in the print dialog, and then print the document.
</p>
<p>
Normally that this function does not return until the rendering of all 
pages is complete. You can connect to the 
<a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation-status-changed" title='The "status-changed" signal'><span class="type">"status-changed"</span></a> signal on <em class="parameter"><code>op</code></em> to obtain some 
information about the progress of the print operation. 
Furthermore, it may use a recursive mainloop to show the print dialog.
</p>
<p>
If you call <a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-set-allow-async" title="gtk_print_operation_set_allow_async ()"><code class="function">gtk_print_operation_set_allow_async()</code></a> or set the 
<a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation--allow-async" title='The "allow-async" property'><span class="type">"allow-async"</span></a> property the operation will run 
asynchronously if this is supported on the platform. The 
<a class="link" href="gtk-High-level-Printing-API.html#GtkPrintOperation-done" title='The "done" signal'><span class="type">"done"</span></a> signal will be emitted with the result of the 
operation when the it is done (i.e. when the dialog is canceled, or when 
the print succeeds or fails).

<p>
The ::paginate signal is intended to be used for paginating a document
in small chunks, to avoid blocking the user interface for a long
time. The signal handler should update the number of pages using
<a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-set-n-pages" title="gtk_print_operation_set_n_pages ()"><code class="function">gtk_print_operation_set_n_pages()</code></a>, and return <a href="http://library.gnome.org/devel/glib/unstable/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a> if the document
has been completely paginated.
</p>
<p>
If you don't need to do pagination in chunks, you can simply do
it all in the ::begin-print handler, and set the number of pages
from there.

Gets emitted when a preview is requested from the native dialog.
</p>
<p>
The default handler for this signal uses an external viewer 
application to preview.
</p>
<p>
To implement a custom print preview, an application must return
<a href="http://library.gnome.org/devel/glib/unstable/glib-Standard-Macros.html#TRUE:CAPS"><code class="literal">TRUE</code></a> from its handler for this signal. In order to use the
provided <em class="parameter"><code>context</code></em> for the preview implementation, it must be
given a suitable cairo context with <a class="link" href="GtkPrintContext.html#gtk-print-context-set-cairo-context" title="gtk_print_context_set_cairo_context ()"><code class="function">gtk_print_context_set_cairo_context()</code></a>.
</p>
<p>
The custom preview implementation can use 
<a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-preview-is-selected" title="gtk_print_operation_preview_is_selected ()"><code class="function">gtk_print_operation_preview_is_selected()</code></a> and 
<a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-preview-render-page" title="gtk_print_operation_preview_render_page ()"><code class="function">gtk_print_operation_preview_render_page()</code></a> to find pages which
are selected for print and render them. The preview must be
finished by calling <a class="link" href="gtk-High-level-Printing-API.html#gtk-print-operation-preview-end-preview" title="gtk_print_operation_preview_end_preview ()"><code class="function">gtk_print_operation_preview_end_preview()</code></a>
(typically in response to the user clicking a close button).
